Referring now particularly to the form of the invention shown in FIGS. 1to 4, a window cleaning device 10 is illustrated, in operative positionon the pane 12 of the lower sash 14 of a window raised slightly toaccommodate the cleaning device. The pane 13 of the upper sash 15 isshown thereabove. The device 10 is placed against shoulder 16 for guidedmovement across the window sills, a portion of the device protrudinginwardly from the window from which handles extend to work the device.

The window cleaning device 10 comprises an elongated generally U-shapedframe 15, of bar metal, square in cross-section, having an elongatedvertical leg portion 17, a horizontal bight portion 19 and a shortervertical leg handle portion 21. An internal cone surfaced metal ring 20is positioned around the bight portion 19 adjacent the short leg portion21. The lbody of the ring 20 is disposed at a slight angle to thehorizontal as viewed in FIG. 1 and turnably carried upon the ring 20, isa plastic wheel or roller 24, FIG. 5, having an integral hub portion 26rotatably supported upon a stub shaft 28 threaded into a hole in thering 20 and engaging the lower face of the bight portion of the frame.The stub shaft 28 is disposed at an angle to the horizontal similarly tothe wheel 24 so that the body of the wheel is also disposed at an angleto the horizontal. The plastic wheel 24 turns on the shaft. A plastichand knob 30 is xed upon the top end of the short leg portion 21 servingas one handle. Another handle member 32 consisting of a metal strap,turned upon itself midway its ends forming spaced parallel arms 34 and aconnection bight portion 36, is pivotally mounted at its spaced freeends on pivot pin 38 extending through aligned holes in the ring andengaging the sides of the bight portion 19 of the U-shaped frame 15, thearms 34 spanning the ring 20 and the bight portion 19 of the frame andthe short leg portion 21.

A squeegee blade device 40 is pivotally mounted on a telescopicextension 17 retained in adjusted position on the free end of legportion 17 of the frame 15 by a hand fastening screw 17, the mountingconsisting of a U- shaped clamp bracket 42 having side portions 44, 44connected by a `bight portion 46 and with extensions 48, 48. Thesqueegee blade device 40 has an elongated rubber blade 50 clamped alongone long edge therebetween the sides 52, 52 of an elongated metal member54. The blade member 54 is pivotally mounted on a pivot pin 56 extendingthrough aligned holes in the clamp extensions 48, 48 and the metal plate54. The rubber blade 50 can extend under the lower edge of the upperwindow pane 13 and out the slightly raised lower window pane 12 at thetop thereof.

The frame 15 with the squeegee device 40 is attached thereto and adaptedto be manually passed across the window panes by grasping the handle 30in one hand and the handle member 32 in the other hand and moving bothhands laterally over the window sill. During this operation, the wheel24 rolls along a shoulder 58 on the window sill and is guided thereby,with the wiper blade 50 in engagement with the outer surface of the pane12 of the lower window pane 12 as seen in FIG. 1. The angled position ofthe wheel 24 facilitates this movement. After making the rst pass andreturn across the top of the window pane 12, the lower pane 12 is raisedto locate the wiper blade 50 thereon for the second pass and returnacross the pane 12. The lower window pane 12 can be again raised forfurther passes of the wiper blade 50 and in this manner continued untilthe full window pane is washed.

According to the invention, it is contemplated that the rubber wiperblade 50 of the squeegee device 40 be moistened. For this purpose, adetergent or water bottle is mounted in upright position above the topof the squeegee device 40 on an elongated bracket frame 62 havinginwardly bent ends 64 and 66, the end 66 being turned upwardly at itsextremity as indicated at 68. The turned up end 68 is inserted into theclamp bracket 42 alongside the top end of the leg portion 17 and isclamped in position by a set screw 69 passing through a hole in thebight portion 46 of the clamp bracket 52. Flange 64 supports the bottle60. The bottle contains detergent or water 70 adapted to ow by gravityonto the wiper 50. The bottle is closed at the top by a removable cap 72having a conical air inlet 74 and has a water outlet 76 in the bottomthereof.

A short water hose 78 has one end attached to the water botttle outlet76 and extending through a hole in the ange 64 of the bottle supportingframe bracket 62. The other end of the water hose is inserted under ametal strap'80 xed over the top end of the blade member 54 of thesqueegee device 40, so that the free end of the hose is in position overwiper blade edge 82, FIG. 5. The water hose 78 passes through a sheetmetal hose clamp 84 xed on the bracket frame 62 by means of a sleeve 86.An integral spring finger 87 normally interlocks with a curved ange 90to squeeze the hose and stop the passage of water therethrough.

An elongated air hose 92 has one end attached to the conical air inlet74 on the removable cap 72 and extends downwardly along the U-shapedframe 1S to the top of the short leg portion 21 thereof where the freeend is supported by a tiltable hose clamp plate 94 clamped to the handle30 by means of a spring bracket 96. The hose clamp 94 has a bent end 98at its lower end, FIG. l, normally pressing against the air hose 92thereby shutting off the entrance of air thereinto from its free end102. By

pressing inwardly on the other end of hose clamp plate 94, the bent end98 moves outwardly away from the air hose permitting air to passtherethrough and upwardly to the top of the detergent bottle 60. Rubberrings 100, 100 on leg portion 17 of frame 15 guides and supports thehose 92 therealong.

With the construction herein set forth, it will be seen that to wash thewindow, the lower sash 14 is opened to allow the washing device 10 to bepassed outwardly over the window sills. The bottom sash is then loweredand the device 10 positioned as shown in FIG. l, with the bight portion19 of the U-shaped rod frame 15 under the lower rail of the lower sash14, with the handles 30 and 32 inside the window and with the squeegee40 in engagement with the pane 12 of the lower sash 14 under the upperpane 13 and at the very top thereof. The wheel 24 is held against theshoulder 58 of the window sill 18 as shown in FIG. l. The operatorgrasps handle 30 with one hand and handle 32 with the other hand andmanually moves the device 10 along the window sills and across the pane12, the wheel riding along the shoulder 58 of the sill and the wiperblade 50 moving across the pane 12. At the start of the washingoperation, the spring iinger 87 is released from its interlock with thecurved flange 90 of the hose clamp 84 whereby pressure of the air hose78 is released. By pressing the hose clamp plate 94 inwardly by the ngerof the hand holding handle 30, the bent end 98 of plate 94 is releasedfrom its engagement with the air hose 92 thereby permitting air to enterthe entrance end 102 of the air hose so that detergent or water may dripby gravity into the water hose 78 onto the upper end of the wiper blade50. The hose clamp 96 is released on the return pass of the device 10over the window pane to withhold the detergent and allow the window paneto be wiped clean ofthe detergent.

An adapter tubular sleeve 104 is shown xed on the bight portion 19 ofthe frame 15 for releasably mounting a third handle 106, FIGS. lA- and4. The sleeve 104 has a slot 108, intersecting one end thereof forreceiving a set screw for removably securing the angled shank 112 of thehandle 106 in position. The handle 106 may be used for manipulating thewashing device 10 when a different handhold is desired.

In FIG. 6, a handle 114 is formed of a flat rectangularshaped plasticplate 116 with a reduced end portion 118 with a hole therein. A U-shapedbracket 120 is slidably mounted on the bight portion 19 of the rod frame15 and has sides provided with aligned holes registering with the holein the reduced end portion of the handle to accommodate a threadedclamping bolt 122 extending through the bracket and handle and securedby a wing nut 124. This handle 114 serves the same purpose as handle106.

A modified window washing device 10' with a slightly different U-shapedframe 15 shown in FIGS. 7 and 10, includes a modified apparatus forholding and supplying water to the Wiper 50 is shown. A different shapedbracket 62' has a bent end 68 clamped in bracket 42 by set screw 69. Theother end of the bracket 62 is bent to provide a support for a waterbottle 60. This bottle is open at the top with a beaded rim 126 and isclosed by a removable cap 72 having a disc-shaped body 128 with adownwardly extending peripheral ange 130 adapted to snap over the beadedrim 126. The cap is retained on the neck of the bottle by ring 132connected to the flange 130 by an integral connecting strip 134. Thebottle 60 has an outlet 60 from which water hose 78 extends and its freeend is secured to the top end wiper blade of plate 52 by a strap 80'.The water hose 78' passes from the outlet in the bottle through achannel-shaped member 138 on the bracket 62 through a transverse hole`139 in the bracket and downwardly therealong in a groove 142 in theother side thereof, and under a metal ring 86' on the bracket 62. A setscrew 144 extending through a hole 86 in the ring engages the water hosein the groove to clamp the hose to cut olf the supply of water to thewiper blade 50. The sliding channel-shaped member 138 has an extensionextending under ring 86 and is bent outwardly at its free end forming anger piece 148 used for sliding the member 138. The plate 138 is held inadjusted position by a set screw 150 on the ring 86.

When it is desired to supply water to the wiper blade 50 set screw 144is turned to release the water hose 78 and cap 72 is opened to admit airto the top 0f the bottle so that water drips from the hose onto thewiper by gravity.

In this form as shown in FIGS. 8 and 9, the bore of the ring 20 on bightportion 19' is tapered as-indicated at 152 instead of being straight asin FIG, 1. Stub shaft screw 28 rotatably secures a wheel 24 to the ring20. The wheel is enclosed with a shell 153 of rubber to have frictionalengagement with sill S. The window washing device 10 is similar todevice 10 and similar reference numerals used to indicate similar parts.By this construction the ring 20 can be angled upon the bight portion1-9 of frame 15 to better adapt the wheel to the sill shoulder 16 andbalance the bottle weight.

In FIG. 11', a window washing device 10" is shown adapted for singlehanded operation inside the window. In this form U-shaped member 15 hasone of its elongated legs 156 clamped in the bracket 42" by set screw 69to support the squeegee device 40". The other leg 158 is grasped by thehand of the operator to manipulate the device 10 of the window pane. Abottle 60 is constructed and supported similarly to the bottle 60" ofFIG. 7, and with the water hose 78' connected to the bottle 60" andwiper 50".

In operation, the U-shaped frame .15 is grasped by the hand and device10 moved across the pane 12" with the wiper 50" wiping the surface ofthe pane, the set screw 144" having first been released and the cap 72"removed from the top of the bottle 60".

" In FIGS. l2 and l5, a different means for operatively connecting oneend of water hose 78a to wiper blade 50a of the squeegee device 40a.Hose 78a is connected to a sleeve 160 having bifurcations 162 which gripthe sides of the U-shaped plate 52a of the squeegee device. Plate 52ahas a hole 164 formed in its bight portion that permits the detergent orwater to seep through on a wiper plate and upwardly and over the top endsurface p 58a' of the blade, the upper of the plates 52a as indicated at52a' rising above the blade top surface 58a" to direct the water flowforwardly over the top surface 58a'.

In FIGS. 16 to 19, a U-shaped frame 175 is formed of rod 0r tubing andincludes a short leg 176 having a handgrip knob 177 at its upper endreceiving a flexible detergent or water delivery hose 178 that isextended into the" knob end of the leg portion 176 and through itscentral hose 179'and outwardly through a side opening 181. The U-shapedframe 175 further has a bight portion 182 adapted to pass under thewindows 12 and 13 which supports by a clip 183 a continuation of thehose 178 which extends upwardly along an outer leg portion 184 of theframe 175 and supported by further clips 185 and 186 thereon. The upperend of the leg portion 184 has an outwardly-extending threaded stud 187over which a telescoping tube 188 extends for a slide fit with the studbeing received in an elongated open ended slot 189. By applying a handnut 191 to the stud 187 the sleeve 188 will be.- retained in itsadjusted position therealong. The upper end of the sleeve 188 is forkedas indicated at 192 and a wiper blade 193 is pivotally connected to thefork end 192 by a pivot pin 194 so that the wiper 193 may readily beaccommodated to the window surface.

The hose 178 is further held upon the sleeve 188 by a clip or band 195and extends upwardly as best seen in FIGS. 17 and 19 for connection to anozzle pipe 196 having a hook end 197 that is tight fitted downwardlyover the metal portion of a wiperblade 193 so as to deliver thedetergent and water forwardly through a small hole or orifice 198 at thehigh point of the hook end 197 onto the top edge of the rubber wiperblade material 199 so as to lubricate and clean the wiper blade andprovide detergent to wash the window surface. The hook end 197 of thenozzle pipe 1'96 is hollow throughout its length but closed at 201, FIG.19, so as to limit the outflow of water `through the opening 198 insmall amounts yet suicient to effect the complete cleaning of the windowsurface.

The detergent and water for this purpose is contained in a bottle 203that is supported by a double bent wire hook bail 204 over a molding 205above the wiper blade 193 outside the window so that the detergent andwater can flow by gravity. The bottle 203 has a nozzle 206 by which thehose tube 178 is connected with the bottle 203.

Under the handgrip knob 177 is secured a plate 207 which can be flexedby depressing with the linger an upturned end 208 of a plate 209 securedby rivets 210 to the depending end of plate 207, An inwardly turned end211 is adapted to engage the hose tube 178 against the short leg portion176 of the frame 175 just below the opening 181 so as to normallymaintain the tube 178 against passage of the detergent and water butwhen flexed by the finger to the position shown in FIG. 16 the water isallowed to pass upwardly through the hose tube 178 to the hook endnozzle pipe 196 and be discharged through its hole 198 over the upperend of the wiper blade 193 and onto the window surface being cleaned.

A U-shaped handle member 214 Similar to that used in the other forms ofthe invention is connected by pivot pins 215 along with a plastic wheel216 in the same manner as described in connection with the other formsof -the invention as shown in FIGS. 5 and 8. The wheel 216 when thecleaning device is put into use abuts shoulder 16 for guided movementacross the window sill S.

All of the above forms of the invention are preferably made from partsof lightweight metal such as aluminum and plastic and which can readilybe handled by the two hands of the operator and retained in the verticalposition against the window surface so that a clean sweep of the windowsurface is eected squarely from one side of the window to the other.when one pass of the cleaning device has been made across the window andreturned without water one portion of the window is cleaned. The lowerwindow 12 is thereafter raised to do the neX-t portion of the window ina similar manner and the iinal cleaning as effected on the last andbottom pass upon the window, the lower window being raised each time.When the upper window is to be cleaned it is brought down to the loweredposition and the lower window will have been raised after being cleanedto the upper position. The top portion of the upper window is then rstcleaned in the same manner with the window being raised and returnedtoward its upper position with each successive cleaning pass of thewiper blade. Finally when both windows have been cleaned the cleaningdevice is unseated from the sill shoulder 16 and drawn inwardly throughopen windows and taken to the next window for cleaning, the windows justcleaned having been closed. The next window will be cleaned in the samemanner.
